RECORDER.

Application filed January 12, 1928. Serial No. 246,322.

'My invention relates particularly to recorders which graphicallyrecord-the synchronized operations of timing mechanism and mechanismsfor inscribing the varia tions in the operations of a motor car or busor other motor driven machine; and has for its object, to combinewiththese mechanisms an instrumentality for inscribing the record on aribbon moved by one of these mechanisms and an instrumentality co-actingwith the inscribing instrumentality and marking the time, such latterinstrumentality being. operated continuously by clock work. Morespecifically stated the operations inscribing instrumentalityconsists'of a vibratory stylus-carrying head and the time insc'ribinginstrumentalities consist-of I upper end of the lever through which thebar carrying the sylus is reciprocated.

Figure 2 is a plan view of the stylus carrying head and illustratingpartly in horizontal sectional view its connection to the operating rodstherefor;

Figure 3 is a side elevation of the stylus carrying head;

Figure 4 is a detail end view of the time 'inscribing rollers ininscribing relation with ghe ribbon and the supporting table there-Figure 5 illustrates particular means for vibrating the stylus carryinghead.

The stylus carrying head with its st lus detachably carried thereby isgoverne as to its movement preferably by the mechanism disclosed in anapplication about to be filed by James Russell Mackenzie Tisdale forLetters Patent for improvements in recorders set forth in thatapplication, and

the time indicating rollers and the mechanlsm for causing the ribbon totravel are also disclosed in the said application.

The stylus carrying head is indicated at Z) and its carrying andoperating mechanism at c. The time indicating rollers are indicated at(5 and c and the pin-like protuberances from their surfaces areindicated at f and g respectively. The roller cl being connected to thehour hand mechanism of the clock is adapted to make one revolutioneachtwentyfour hours and has twenty-four ofthe radial pin projectionsarranged in spiral series around the roller and extending from one endto theother; and the pins of roller 6 are in number and also arranged inspiral series as shown in Figure 1. The effect is that as the rollersrotate 'each pin individually. and successively touches the movableribbon whether the latter is moved or not, and as the ribbon feedingmechanism is operatedby the driving mechanism of the car, bus or othermachine through transmission mechanism, the pins being arranged spirallyalong the rollers each roller inscribes on.

the ribbon a straight line transversely across it and spaced a distanceapart corresponding with the distance the rollers are separated fromeach other. When the ribbon is moving, the rollers, through their spiralseries of pins, inscribe a positive line. The spiral series of pins 7being twenty-four in number while the spiral series of pins g are sixtyin number, the lines i scribed are slightly different in appearance.This dif ference-is enhanced by the fact that the sixty pin roller,which inscribes a minute lin'e, owing to the pins being sufficientlyclose together, presents what is-in eifect a double line, while the pins7 of the roller (2! inscribe a single line. 1

The vibrator head I) is preferably made of.metal and tile stylus i is ofbrass. The head is split as at j to form jaws'for gripping the stylusand a clamping screw is clamps the jaws together. holding the stylusrigidly between them. The body of the stylus head is split as at m atits opposite end to a short distance beyond its middle and near thisinner end the stylus head is bored V as at 0 to receive one end of theoscillatory rod p carried in a slide rod 9 carried in turn ,slidably ina sleeve 8 secured rigidly as at t and fro in proportion to the speed ofthe 4 contraction of the governor.

the lever is forked and engages the pin to the frame of the machine. Thesleeve has a slot 6 through which a block u is con-- motor andconsequently to the expansion and 3 through which the rod 9 isreciprocated and 'the car or bus or other machine.

the stylus moved proportionately. The oscillatory rod 27 has a collar 2secured to it to prevent the relative axial movement of this rod 79 inthe slide rod 9 while collars 3 and 4 mounted on'and encircling theslide rod kecpthe oscillatory rod in its groove in the slide rod. Thisoscillatory rodis oscillated through the medium of one'of its ends whichis bent to goose-neck form as at 5 and has one end in slidableengagement with a slot 6 in a guide bar 7 carried by a verticallyreciprocating bar 8 attached at its lower end as at 9 to a spring 10fastened as at 11 to the frame of the recorder. The upper end of thisvertical bar 8 is guided in a bracket 12 and it is vibrated by aneccentric 13 on a shaft 1,4 bearing on the spring during each revolutionof the shaft 14 thus depressing the spring and releasing it alternately;The

effect is'that when the spring is released it lifts the bar 8 which islowered by the eccen-- tric and its raising and lowering is more or lessrapidly repeated by rotation'of the shaft 14 which is connected to thedriving gear of As the bar 8 is vibrated in this manner the guide bar 7carried by it transmits the vibrations to the goose-neck end 5 of bar 1)thus vibrating it and the stylus carrying head I) and'through itthe'stylus The ribbon is printed with longitudinal time indicatingdivisions 17 land transverse divisions 18 and sub-divisions 19 ofdistance. This vibrating of the stylus while the ribbon is movinginscribes a path on the ribbon graphically presenting with This end of.

the other markings in the ribbon the variations in the speed of-the caror bus.

These instrumentalities coact with the ribbon and their variousoperating mechanisms and the divisions bf the ribbon are coordinated toproduce an accurate record.-

Although I have described and illustrated the structural featurescoactin with the ribbon other than the stylus and its-'vibratingmechanism and the time indicating rolls I do not claim other than theparticular stylus carrier and vibratory mechanism and the timeinscribing rollers as the said other mechanism forms a part ofthesubjcct-matter of the separate application filed by James RussellMackenzie Tisdale, before mentioned.

What I claim is as follows In a recorder for inscribing a readilreadable record of time, distance and spee having a record ribbondivided and sub-divided into representations of divisions of distanceandtime; an oscillatory stylus for inscribing a path on the'ribbon, andtime inscribing instrumentalities -coacting and synchronized withthe'ribbon and vibratory stylus, a stylus carr ing rod havin a lateralextension, for osci lating the sty us carrying rod; a verticalreciprocal bar; a guide gitudinal slot, exten ing parallel to the rodand slidably engaged by the lateral extenosion of the. stylus carr ingrod; a shaft; an eccentric cam inounte upon and rotatable with theshaft; a spring secured at one end and having its 0 posite enddisposed.in position to be acted u bar carriedrigidly b the bar-having a lon-'pon b the eccentric cam and having the lower en of the vertical barconnected thereto for the purpose of causing thevertical bar to bealternately lowered and raised, thereby oscillating the stylus Vcarrying rod.

In testimony whereof I have signed my name to this .specification.--

-- I CHARLES H 'lAYLOR.
